The sum of two vectors A and B is at right angles to their difference. Then

A

A=B

B

A=2B

C

B=2A

D

A and B have the same direction

Text Solution

Verified by Experts

The correct Answer is:
A
`(A+B) _|_ (A-B)`
`:. (A +B).(A-B) = 0`
`:. A^2 + BA cos theta - AB cos theta - B^2 = 0`
or `A =B` .
